Specification forming part of Letters Patent No. 50,842, dated November 7, 1865.

To all whom it may concern:

Be it known that I, ALMoN J. PRESTON, of Dryden, in the county of Tompkins and State of New York, have invented a new and useful Improvement in Blame-Fasteners, and I do hereby declare thatthe followin gis afull,clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specitication, in which Figure l represents a central longitudinal section, showing the shell A, hooks B, and the hooked teeth a on its inner surface; also, the sliding hook C, having` corresponding teeth c in its shank C, and in the position it is in when in use. D is a loop on the end of the shell A,Figs. 1,2, and 3, under which the shank ofthe sliding hook C is introduced; G, aspring riveted to the outer side of the shell A. By means of the pins H H the hooks B and C are fastened to the rings or staples of the haines.

Fig. 2 represents a view of the convex side, with the hooks B and C removed, and showing the sliding band E, loop D, (and ring' F for pole-strap.) The dotted lines show the posiiion of the sliding band E when the shank C".

is being crowded into place, then slipped back to its place, as shown in the drawings, thus inelosing and holding firmly together the shell A and shank C". The teeth a a and c' c engaging each other, the two hooks B and C cannot be withdrawn until the band E is again slipped back to the position of the dotted lines, which must he done when the hames are to he unfastened. The spring G is to hold the band E in either position.

Fig. 3 is an end view ot' the shell A and loop D.

Fig. 4 is a cross-section of the shell A and shank C of the sliding hook G near the loop D.

I do not claim a curved rack fitted to traverse in a groove provided with a vibrating catch operated by a spring; but

I do claim- The combination of all the parts as described, except the ring F, and for the purpose of fastening haines.
